I mean, I dunno if skybasing is only in solo. I've been playing on CC for a bit over a year now I believe, so do with that as you wish.
I don't have experience with Solo, but I have played Dwarven multiple times. There's two Iron gens, and once they're at Lvl 2 it doesn't take long to get geared up. The dragon can be used as a advantage too, especially if part of it is close to an island.
Also, suggesting they add "x" amount of maps really doesn't help.
The Oriental suggestion I'm kinda indifferent about, but it's really convenient to grab Iron and be able to gear up quickly.
